Vincristine induced cranial neuropathy

Area of Science:

• Neuro-oncology
• Clinical Neurology
• Pharmacology

Background:

• Vincristine is a common chemotherapy agent used in various cancers.
• Peripheral neuropathy is a known adverse effect of vincristine treatment.
• Cranial neuropathies are less frequently reported but significant toxicities.

Observation:

• This study presents three cases of patients developing cranial neuropathy during vincristine therapy.
• The cranial nerve involvement was observed in a mostly bilateral pattern.
• Potential for misdiagnosis exists due to overlapping symptoms with primary tumors or metastases.

Findings:

• Vincristine-induced cranial neuropathy can manifest during treatment.
• Prompt identification of this reversible neurological dysfunction is possible.
• Literature review supports the occurrence of these rare toxicities.

Implications:

• Highlights the importance of vigilant monitoring for cranial nerve toxicities in patients receiving vincristine.
• Emphasizes the need for differential diagnosis to avoid misattributing symptoms to disease progression.
• Suggests that early detection and management can improve patient outcomes and prevent long-term deficits.
